Question

elements belonging to the same group have same valency​

Answer 1

Answer ⤵️

➡️True

(1) The valency of an element is determined by the number of valence electron in the outermost shell of an atom of an element. (2) All the elements in a group have the same number of valence electrons. Therefore, elements in the same group should have the same valency. ... Similarly for group II, the valency is two.

Answer 2

Answer:

Elements belonging to the same group have the same valency because the

number of valence electrons in a group is same due to which the tendency of an

atom to lose or gain electrons in order to attain nearest noble gas configuration

is also same.
